Change in plans. Another new build begins

Dang, I look at the pictures, then I look at the pushmobile here in the shop and I wish I would have kept that stuff. Did okay for what it is, but those 598s and 632s are brutal. Compression, cam and heads and I think it would have perked it up.
Hi Cole is that block front oiled. Can you explain the main oil line routing in the valley area. Are the lines going to the rocker feeds teed off the line as well. Hard to tell without better pic. Are the cam bearings restricted in the main bearing saddles and if so what size.
The line in the valley again, is it coming in from the back of the block from a bulkhead fitting?
Where does the second smaller line go to that comes off the oil filter adapter.
